The directory structure looks OK as far as it goes. You don't give any indication of what's in your web.xml. Have you mapped your servlet(s) to a URL path? Are you using the correct mapped path in your HTML? Do you get any errors in the container log files?

Hi Michael! 1.Open web.xml available under <Servlet Installation Directory>/conf 2.Set url-pattern to /servlet/* for servletname "Invoker" under servlet-mapping tag. Save this file. call in the browser :http://ipaddress ortno/servlet/<here name of the servlet>
